But there's another way: WindizUpdate is a site that allows you to install Windows updates using Firefox and Opera. It installs a plug-in that detects what updates you need to install, downloads the setup for each update and installs them. It may not be official, but:

* updates are downloaded from Microsoft's site* it doesn't collect personal identifiable information* it doesn't require Windows Genunine Advantage and it doesn't install it* you don't have to use Internet Explorer, neither the ActiveX for Windows Update* you don't get dialogs that prompt you to restart the computer

If you still don't trust the site, you can find a forum where you can post questions or read other people's problems, without creating an account.

There are other ways to install the updates for Windows, but this is a great alternative to Microsoft's Windows Update."
